HEADLAMP (HALOGEN TYPE)

Component Description

INFOID:0000000004216357

LOW BEAM OPERATION

When the lighting switch is in 2ND position, the BCM receives input requesting the headlamps to illuminate.

This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R

controls the headlamp low relay coil which supplies power to the low beam headlamps. 

HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION

With the lighting switch in the 2ND position and placed in HIGH position, the BCM receives input requesting

the headlamp high beams to illuminate. The flash to pass feature can be used any time and also sends a sig-

nal to the BCM. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU

of the combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R

controls the headlamp high relay coil which supplies power to the high beam headlamps.

The combination meter receives a high beam request signal (ON) through the CAN communication lines and

turns the high beam indicator lamp ON.

System Description

INFOID:0000000004216359

The headlamp system for Canada vehicles is equipped with a daytime light control unit that activates the high

beam headlamps at approximately half illumination whenever the hybrid system is operating. If the parking

brake is applied before the hybrid system is started the daytime lights will not be illuminated. The daytime

lights will illuminate once the parking brake is released. Thereafter, the daytime lights will continue to operate

when the parking brake is applied.

Component Description

INFOID:0000000004216361

After starting the hybrid system with the parking brake released and the lighting switch in the OFF or 1ST posi-

tion, the headlamp high beam automatically turns on. With the lighting switch in the 2nd position or with auto-

lamps ON, the headlamps function the same as conventional light systems.

OPERATION

The BCM monitors inputs from the parking brake switch and the combination switch to determine when to acti-

vate the daytime light system.  The BCM sends a daytime light request to the IPDM E/R via the CAN commu-

nication lines.  The IPDM E/R grounds the daytime light relay which in turn, provides power to the ground side

of the RH high beam lamp.  Power flows backward throught the RH high beam lamp to the IPDM E/R, through

the high beam fuses, through the LH high beam lamp circuit to the LH high beam lamp and on to ground.  The

high beam lamps are wired in series which causes them to illuminate at a reduced intensity.
